GB/T 3766-2015 in English

《GB/T 3766-2015液压传动 系统及其元件的通用规则和安全要求》由TC3（全国液压气动标准化技术委员会）归口，TC3SC1（全国液压气动标准化技术委员会液压传动和控制分会）执行，主管部门为中国机械工业联合会。
本标准规定了用于GB/T 15706-2012中3.1定义的机械上的液压系统及其元件的通用规则和安全要求。本标准涉及到与液压系统相关的所有重大危险，并规定了当系统安置在其预定使用的场合时避免这些危险的原则。

1 Scope

This standard specifies general rules and safety requirements for hydraulic fluid power systems and components used on machinery as defined by GB/T 15706-2012, 3.1. It deals with all significant hazards associated with hydraulic fluid power systems and specifies the principles to apply in order to avoid those hazards when the systems are put to their intended use.

Note 1: See Clause 4 and Annex A for the content related to significant hazards.

The significant hazard noise is incompletely dealt with in this standard.

Note 2: Noise emission depends especially on the installation of hydraulic components or systems into machinery.

This standard applies to the design, construction, installation and maintenance of hydraulic systems and their components, also taking into account the following aspects:

a) assembly;

b) installation;

c) adjustment;

d) operation;

e) maintenance and cleaning;

f) reliability;

g) energy efficiency;

h) environment.
